中文摘要:
      勉县俞家坪铅锌多金属矿位于勉略康构造混杂岩带东段。区内泥盆系金家河岩组铅、锌、银、金等元素背景值高,铅锌多金属矿成矿物源丰富。区内北西向断裂构造为矿液提供了运移通道和就位空间。华力西—印支期中酸性侵入岩体为成矿物质的迁移、富集提供了动力。银、铅、锌、金地球化学异常发育,成矿地质条件十分有利。通过工作在区内发现多条铅锌多金属矿体,找矿前景看好,赋矿岩性主要为金家河岩组蚀变白云质灰岩,矿体受北西断裂控制,矿床成因类型为热液型。
英文摘要:
      Mianxian yujiaping lead-zinc polymetallic ore deposit is located in the eastern part of mianluekang tectonic hybrid rock belt. There is a high background of elements such as lead, zinc, silver and gold in the devonian jinjiahe formation, and lead-zinc polymetallic ore is rich in mineral resources. The northwest fault structure in the area provides migration channel and emplacement space for ore fluid. The hualixi-indosinian intermediate acidic intrusions provide the power for the migration and enrichment of ore-forming materials. The geochemistry of silver, lead, zinc and gold are abnormal, and the ore-forming geological conditions are very favorable. A number of lead-zinc polymetallic ore bodies were found in the area, and the prospect of ore prospecting was promising. The lithology of the ore body was mainly altered dolomite limestone in the Jinjiahe formation, and the ore body was controlled by the north west fault, and the genesis type of the ore deposit was hydrothermal type.
